Re: 1981 CB650c Won't Start

Since the bike won't run correctly as long as either problem exists, they are both equally important. The seats are not removable, and there should not be an o-ring or anything else in them. When you clean them, they should shine like new pennies. I use cotton swabs and a product called Nevr-dull. N...

Re: CuzYNot's carb jets

I took this pout of the carb manual thread and made it into a thread of it's own. Take a look at the side of one of your carb bodies. Your bike should have VB44A carbs. If they are from the 82 model, as CB650 suggested above, they will be VB44C carbs. If there is any other model number on them, tell...

Re: Starter clutch issues

Welcome to the forum!

Are you certain that the problem is not with the solenoid? Try bridging the gap between the two posts and see if the starter turns.

Re: 1981 CB650c Won't Start

Don't worry about bending any tabs. Your issue is definitely with those float needles. Also, the plastic floats you have are not adjustable. If you put the float needles side by side, are they the same size? If not, what is down in the needle seat that is keeping them from going all the way in? Spra...

Re: 1981 CB650c Won't Start

Did your kits include new float needles? If not, check the ones on the "floppy" floats and make sure the spring in the needle is springy. Also, try tapping on the float bowls with a screwdriver handle or something similar. Often this is all it takes to make them seat and stop leaking. The ...

Re: New Fork Seals - Did I just screw up my forks???

I've always slide-hammered them apart. Did you see the manual here in the General Discussion forum? On page 111, it talks about replacing the fork seals.

Re: Carburetor swap?

The CB750 and CB900 carbs function different internally. The CB650 carb have one main jet, while the larger engine carbs have primary and secondary main jets. The larger bikes also used DOHC engines, so I doubt the intakes would line up correctly (Note that I've never tried to see how they'd fit).

Re: Carburetor swap?

Cant say for sure. In 1983 the 650 Nighthawk switched to a double overhead cam engine. The cylinder heads are different, so the spacing may also be different.

Re: Carburetor swap?

Mostly that it will need to line up with the cylinder head. There may be some that will work, but the only one I know of is the Nighthawk.

Re: Carburetor swap?

Your bike has VB44A Carbs. The 81 and 82 CB650 and CB650C are the only bikes that used these carbs. The only others that I know would be compatible are the VB43C carbs from the 1982 Nighthawk 650.

Re: 1981 CB650c Won't Start

Have you checked out the carb cleaning manual here in the General Discussion forum? The carbs wont be exactly like your's, but the techniques are basically the same. Drop about a tablespoon of oil in each cylinder through the spark plug hole. If the compression improves, your problem it most likely ...
